摘要：The whole set of astrophysical data indicates that our Universe is globally
baryon asymmetrical. Nevertheless a possibility of existence of relatively small amount
of suciently large antimatter regions is not excluded. Such regions can survive the
annihilation with surrounding matter only in the case if their sizes exceed a certain scale.
It is shown that quantum fluctuations of a complex scalar eld caused by inflation can
generate large antimatter domains progenitors, which contribute insigni cantly to the
total volume of the Universe. The resulting distribution and evolution of such antimatter
regions could cause every galaxy to be a harbour of an anti{star globular cluster. The
existence of one of such anti { star globular cluster in our Galaxy, does not contradict
the observed { ray background, but the expected fluxes of 4He and 3He from such an
antimatter object can be searched for in PAMELA experiment and are de nitely accessible
for the sensitivity of coming AMS02 experiment.
